3 This is the GRUB. Welcome.
5 This file contains instructions for compiling and installing the GRUB.
10 GRUB depends on some software packages installed into your system. If
11 you don't have any of them, please obtain and install them before
17 * GNU binutils 2.9.1.0.23 or later
18 * Other standard GNU/Unix tools
19 * LZO 1.02 or later (optional)
21 * Autoconf 2.59 or later
26 The `configure' shell script attempts to guess correct values for
27 various system-dependent variables used during compilation. It uses
28 those values to create a `Makefile' in each directory of the package.
29 It may also create one or more `.h' files containing system-dependent
30 definitions. Finally, it creates a shell script `config.status' that
31 you can run in the future to recreate the current configuration, a
32 file `config.cache' that saves the results of its tests to speed up
33 reconfiguring, and a file `config.log' containing compiler output
34 (useful mainly for debugging `configure').
36 If you need to do unusual things to compile the package, please try to
37 figure out how `configure' could check whether to do them, and mail
38 diffs or instructions to the address given in the `README' so they can
39 be considered for the next release. If at some point `config.cache'
40 contains results you don't want to keep, you may remove or edit it.
42 The file `configure.ac' is used to create `configure' by a program
43 called `autoconf'. You only need `configure.in' if you want to change
44 it or regenerate `configure' using a newer version of `autoconf'.
50 The simplest way to compile this package is:
52 1. `cd' to the directory containing the package's source code and
53 type `autogen.sh' and then `./configure' to configure the package
54 for your system. If you're using `csh' on an old version of
55 System V, you might need to type `sh ./configure' instead to
56 prevent `csh' from trying to execute `configure' itself.
58 Running `configure' takes awhile. While running, it prints some
59 messages telling which features it is checking for.
61 2. Type `make' to compile the package.
63 3. Optionally, type `make check' to run any self-tests that come with
66 4. Type `make install' to install the programs and any data files and
69 5. You can remove the program binaries and object files from the
70 source code directory by typing `make clean'. To also remove the
71 files that `configure' created (so you can compile the package for
72 a different kind of computer), type `make distclean'. There is
73 also a `make maintainer-clean' target, but that is intended mainly
74 for the package's developers. If you use it, you may have to get
75 all sorts of other programs in order to regenerate files that came
76 with the distribution.
79 Compiling For Multiple Architectures
80 ====================================
82 You can compile the package for more than one kind of computer at the
83 same time, by placing the object files for each architecture in their
84 own directory. `cd' to the directory where you want the object files
85 and executables to go and run the `configure' script. `configure'
86 automatically checks for the source code in the directory that
87 `configure' is in and in `..'.
93 By default, `make install' will install the package's files in
94 `/usr/local/bin', `/usr/local/man', etc. You can specify an
95 installation prefix by giving `configure' the option `--prefix=PATH'.
97 You can specify separate installation prefixes for
98 architecture-specific files and architecture-independent files. If
99 you give `configure' the option `--exec-prefix=PATH', the package will
100 use PATH as the prefix for installing programs and libraries.
101 Documentation and other data files will still use the regular prefix.
103 In addition, if you use an unusual directory layout you can give
104 options like `--bindir=PATH' to specify different values for
105 particular kinds of files. Run `configure --help' for a list of the
106 directories you can set and what kinds of files go in them.
108 If the package supports it, you can cause programs to be installed
109 with an extra prefix or suffix on their names by giving `configure'
110 the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
112 Please note, however, that the GRUB knows where it is located in the
113 filesystem. If you have installed it in an unusual location, the
114 system might not work properly, or at all. The chief utility of these
115 options for the GRUB is to allow you to "install" in some alternate
116 location, and then copy these to the actual root filesystem later.
122 If you want to set default values for `configure' scripts to share,
123 you can create a site shell script called `config.site' that gives
124 default values for variables like `CC', `cache_file', and `prefix'.
125 `configure' looks for `PREFIX/share/config.site' if it exists, then
126 `PREFIX/etc/config.site' if it exists. Or, you can set the
127 `CONFIG_SITE' environment variable to the location of the site script.
128 A warning: not all `configure' scripts look for a site script.
134 `configure' recognizes the following options to control how it
138 Use and save the results of the tests in FILE instead of
139 `./config.cache'. Set FILE to `/dev/null' to disable caching, for
140 debugging `configure'.
143 Print a summary of the options to `configure', and exit.
148 Do not print messages saying which checks are being made.
151 Look for the package's source code in directory DIR. Usually
152 `configure' can determine that directory automatically.
155 Print the version of Autoconf used to generate the `configure'
